Trinity College of Cambridge University has a fantastic online collection of medieval manuscripts, specifically, The James Catalogue Of Western Manuscripts. Of particular interest (so far! I look forward to more browsing) is Trinity Manuscript B.11.22. I found out about this manuscript from J.K. Petersen at the Voynich Portal.
This is a prayer book written in Latin and Medieval Dutch, in the 13th and 14th centuries. And it is chock full of lions, lion-human bipeds, and full-out sagittaries. Here, enjoy ...
From page f115r, a lion running along the top of a page.
From page f083r, a small lion being chased by a guy with an axe! I like the slight smile on the lion; he knows he's getting away!
From page f155v, a lion ripping the heck out of a bunny and gnawing on its face. Assuming the monkish artist knew the size of a bunny, he evidently had a funny idea about how big lions are!
Funny Two-Legged Lion People!
From page f142v, a lion soldier in chain mail shooting an arrow.
From page f153r, this one is ready for war with shield and a pole arm.
From page f147r, a sagittary archer with a floral tail-tuft.
From page f003r, another sagittary archer, somewhat worn by the ages.
From page f191v, a liontaur with an evil-looking black sword and a funny hat.
From page f201v, a liontaur sounding a horn.
From page f141r, the piece of resistance! Please allow me to present the most noble Archbishop of Taurs!
